Definitions

  • the present invention relates to the commercial processing of plant-based food materials.
  • the invention relates to the use of low frequency ultrasonic energy to modify the viscosity of purees of plant-based food products.
  • the rheology, and especially the viscosity, of plant-derived food products is a key parameter in determining consumer acceptance of the food product. This is due to the influence of viscosity on visual appearance, mouth-feel and flavour release.
  • Part of the viscosity profile of the food product is derived from insoluble tomato solids consisting of pectins, hemicelluloses, cellulose, proteins and lignin. These insoluble components exist in a continuous aqueous matrix of soluble pectins, organic acids, sugars and salts.
  • the rheology of the paste may be augmented by increasing the vegetable matter content of the product.
  • this will tend to lead to unacceptable increase in formulation cost where these products are manufactures on a commercial/industrial scale.
  • Such processes may have a limited viscosity modifying effect in higher moisture content products, such as fruit juices. This lack of effectiveness for higher solids purees is due to the limited level of localised pressure fluctuations that can be produced by these processes, usually in the order of 400 kPa for high-shear mechanical homogenisers.
  • a method for modifying the viscosity of pureed vegetable matter including the step of applying low-frequency ultrasonic energy (having a frequency in the range from about 16 kHz to 100 kHz) to said puree via a sonotrode, wherein cavitation of water substance in said puree is induced, thereby to degrade the cellular structure of the vegetable matter and to degrade the cell wall material of the vegetable matter.
  • low-frequency ultrasonic energy having a frequency in the range from about 16 kHz to 100 kHz
  • Ultrasound is defined in the art as sound waves having a frequency above the threshold of human hearing. It can be subdivided into three frequency ranges: Low frequency, or 'Power' ultrasound: 16 - 100kHz; High frequency ultrasound: 100kHz - 1 MHz; and Diagnostic ultrasound: 1 - 10MHz.
  • Low frequency ultrasound energy effects chemical or mechanical changes by generating micro-bubbles within an aqueous liquid/slurry reaction medium, a process called cavitation.
  • the sound acts as a source of vibrational energy, which causes the molecules in the liquid to vibrate. This alternately compresses and stretches the liquid's structure to produce steam bubbles, as the internal fluid pressure instantaneously drops below the vapour pressure at the local temperature.
  • thermodynamic conditions within these collapsing bubbles can be extreme, with temperatures of 5000K and pressures of up to 2000 atmospheres being achieved. As they collapse, the bubbles release energy. This is the energy that is utilized by the invention to effect changes in the structure of the vegetable material, in turn affecting its rheology.
  • the method according to the invention advantageously allows target viscosity to be achieved without necessarily using thickening additives, as it has been found that a low-frequency ultrasonic standing wave treatment of either the vegetable component of the food product, or of the whole food product, results in an increase in product viscosity.
  • the exact mechanism for this viscosity increase is not precisely known, but it is suspected that the energy released during collapse of the cavitation bubbles increases the surface area of the insoluble components of the vegetable cell structure, resulting in an increased interaction between the insoluble solids and the continuous aqueous matrix and also between neighbouring insoluble particles, such as an increased ability for the insoluble molecules to absorb water molecules.
  • the hydrophobicity of the plant surface layer of some purees means that cavitation may not be achievable at the plant molecule surface, especially where prior art apparatus is used. Therefore, immersion of the low- frequency sonotrode in the puree itself is particularly advantageous as it then is capable of delivering a higher energy intensity ultrasonic wave into direct contact with the plant structure surface, facilitating more efficient energy transfer into the product.
  • This sonotrode positioning has the additional advantage of the creation of high velocity 'microstreaming' of fluid surrounding the plant material surface. 'Microstreaming' is effectively localised water micro-currents reaching speeds of up to 780 km/hr, which assist the transfer of energy to the plant cell structure. More preferably, the sonotrode is capable of delivering ultrasound waves having an amplitude of between 1 and 500 micron, as these amplitudes will tend to provide still greater efficiency of energy transfer to the vegetable material.
  • the sonotrode is a radial sonotrode, for example a cylindrical sonotrode which emits the ultrasonic energy radially (ie perpendicular to its axis).
  • the sonotrode is a focussed sonotrode, for example a cylindrical sonotrode which emits the ultrasonic energy from its extremity (ie parallel to its axis).
  • Suitable materials of manufacture of the sonotrode include titanium, aluminium, steel, hastalloy, ceramic material and glass.
  • the ultrasonic energy can be supplied at the frequency, appropriate to the vegetable material, to produce a resonant standing wave (the 'ultrasonic resonance frequency' of the material), the efficiency of penetration of the energy into the structure of the material is greatly enhanced.
  • improved performance of the inventive method may be achieved by the introduction of an automatic frequency scanning system for different types of products.
  • Varying puree material parameters, such as solids concentration, viscosity and the relative composition of plant materials in the puree, will affect the ultrasonic resonance frequency of the puree.
  • the ultrasonic resonance frequency is the frequency at which it is possible to achieve a standing ultrasonic wave in the material, and at which the most effective penetration of energy to the cell structure will be achieved.
  • the ultrasonic resonance frequency may change due to the changing composition of the puree.
  • an automatic frequency scanning system in conjunction with said sonotrode, so that said method also includes the steps of: actuating said automatic frequency scanning system to scan said puree for the ultrasonic resonance frequency, being the frequency at which said puree will support a standing wave of ultrasonic energy; and adjusting the ultrasonic wave frequency delivered by the sonotrode to match said ultrasonic resonance frequency.
  • the ultrasonic system may be actuated to detect the resonance frequency of the specific product, and then re-scan for the new resonance frequency every 0.001 second throughout the treatment process. If the ultrasonic unit does not have the resonance frequency tracking system for different products, then where there is as little as 10 Hz variation from the resonance frequency, this may result in a drop in energy efficiency of the process in the order of 10 - 40%.
  • the resonance frequency of lettuce is typically about 20,350 Hz
  • tomato sauce will have a typical resonance frequency of about 20,210Hz.
  • the method defined above has been found to be particularly useful where the vegetable puree is made up at least partly of tomato puree.
  • the inventive method is advantageous where the vegetable matter is a tomato puree containing between 4°Brix and 36°Brix net total tomato solids.
  • Such products include, but are not limited to tomato sauce, pasta sauce, salsa and ketchup.
  • the puree is heated to a temperature in the range 65°C to 80°C prior to the application of the ultrasonic energy. This is thought to melt the pectin material in the puree and assist in the breakdown of the puree cellular material.
  • the performance of the sonotrode can be enhanced where the puree is placed under an overpressure, particularly an overpressure of between 0.1 Bar and 10 Bar. Overpressure tends to causes an increase in load on the ultrasonic transducer and this produces a greater draw of energy therefrom, which can assist in improving the energy efficiency of the process.
  • apparatus for increasing the viscosity of pureed vegetable matter, via the application of a standing wave of low-frequency ultrasonic energy, said energy having a frequency in the range from about 16 kHz to 100 kHz, to said puree, said apparatus including a sonotrode, wherein said sonotrode induces cavitation of water substance in said puree, thereby to degrade the cellular structure of the vegetable matter and optionally the cell wall material of the vegetable matter.
  • the apparatus and/or the puree conforms to any described above.
  • said apparatus is capable of being retrofitted to a bath, trough, chamber, pipe, flow cell or other vessel capable of containing or transporting said puree for use in modifying the viscosity of said puree.
  • the apparatus may be used to modify the viscosity of vegetable puree as said puree flows in a continuous manner through a fluid flow conduit, such as a pipe.
  • the usefulness of ultrasonic energy in processing vegetable puree material depends upon two main criteria being met: a liquid medium must be present in the puree (even if the liquid element forms only 5% of the overall puree mass) and a source of high-energy vibrations (the ultrasound).
  • the vibrational energy source will be a transducer of which there are two main types: piezoelectric and magnetostrictive, the latter being less adaptable but more powerful than the former. Piezoelectric transducers are the most commonly used.
  • the transducer is functionally connected to a sonotrode, which is the part of the apparatus which physically delivers the ultrasonic energy to the puree.
  • the sonotrode In order to effect the inventive method it is necessary for the sonotrode to be brought into contact with the puree material, whether as a stationary batch or as a continuously flowing material in a conduit, and to actuate the energy supply to the puree via the transducer.
  • a permanent viscosity increase in the puree is generally obtained as a result of the application of ultrasonic energy.
  • the second factor is the application of fluid shear after the ultrasonic treatment. Fluid shear reduces viscosity, presumably by promoting contact of insoluble component with itself, allowing it to re-bond rather than to bond with the continuous aqueous matrix.
  • An outline of typical commercially available equipment that may be used to carry the invention into effect includes:
  • a power source a transducer converting electric energy into mechanical vibrational energy; a sonotrode, which transmits the vibrational energy into the puree.
  • the sonotrode may provide either radial wave, stationary wave or focused emission, depending on the specific application.
  • the sonotrode material can be made of titanium (preferentially) or alternatively ceramic, steel, hastalloy, aluminium or glass.
  • the transducer system may be a PZT (piezo ceramic transducer), a Terfenol-D magnetostrictive transducer or a Nickel/lron/Vanadium magnetostrictive material.
  • the transducers/power supply should have an individual power ranging from 100 W to 8000 W, or higher.
  • the power supplies of most commercially available transducers have automatic resonance frequency tracking, so that when the equipment is running during the thickening process, the unit is also always scanning the new resonance frequency (relates to maximum power output) due to changes in the puree's chemical composition.
  • the sonotrodes/transducers can be mounted or retrofitted to tanks, vessels (round, square or oval), troughs, pipes, or flow-cells containing the tomato based products.
  • Radial sonotrodes may be fitted longitudinally or laterally within an open tank, trough or flume.
  • Reflector shields may be positioned at the base to reflect and or focus ultrasonic energy into the product flow path, which may be at the solvent surface or immersed below the surface.
  • Radial sonotrodes may be fitted in closed flow through cells.
  • the sonotrode design may be modified to enhance the thickening efficiency of the ultrasonic energy.
  • the inclusion of reflector shields may also assist in improving the efficiency of the process.
  • Focused sonotrodes may also be fitted in a flow-through cell, where the puree flows either directly into the face of, or across the face of, the sonotrode. Residence time can be controlled by regulating the micro-streaming flow from the sonotrode, the puree flow rate and by selecting appropriate cell dimensions. Occasionally, a reduction in the viscosity of the puree may be observed after the ultrasonic treatment. Two factors have been observed to affect the extent of this viscosity decrease. The first of these is the composition of the continuous aqueous matrix. It is hypothesized that the insoluble fraction is partially electrostatically bonded and that sugars and salts present in the continuous aqueous matrix partially stabilize the increased surface area structure of the insoluble component, hindering its collapse. Raising the salt and particularly the sugar composition of the continuous aqueous phase hence reduces the viscosity reduction observed after the ultrasonic treatment. EXAMPLE
  • Ketchup A was mixed using a conventional hand-blender, heated to 77°C and cooled to room temperature.
  • Ketchup B was mixed using a conventional hand-blender, heated to 77°C and treated with ultrasonic energy.
  • the ultrasonic energy was supplied by a UP400S Sonicator, obtained from Dr. Hielscher GmbH, of Wartherstrasse 21 , 14513 Teltow, Germany.
  • the Sonicator was fitted with a H22D sonotrode, which was attached to a D22K flowcell.
  • the heated Ketchup B was passed twice through the D22K flowcell at a flowrate of 0.38 kg/min, and under a pressure of 50kPa.
  • the frequency of the ultrasonic energy was approximately 20 kHz during the treatment, and maximum amplitude of the ultrasonic equipment was applied.
  • the treated Ketchup B was then cooled to room temperature.
  • the Ketchup B formulation represents an approximately 10% raw material cost reduction compared with the Ketchup A formulation.
  • Adding soluble components such as sugar and acetic acid to homogenised tomato products assists in stabilising the viscosity increase. This is most likely due to hydrogen bonding between the soluble components and the tomato cell fragments, preventing the fragment surfaces from re-compacting.
  • inventive processes and apparatus disclosed above can be applied with similar success to a wide variety of other plant-based materials, especially those whose cellular structure contains pectin. It will also be noted by those skilled in the art that other mechanical configurations of the ultrasonic equipment may be contemplated while remaining within the scope of the invention.
